State Overview
Property Taxes in Delaware
Delaware's Property Taxes: Nation's Most Affordable
Delaware homeowners pay an average effective tax rate of 0.510%, nearly half the national median of 1.03%—making it one of the lowest-tax states in America. At $1,649 in median annual property taxes, Delaware residents pay less than two-thirds what the typical American household pays ($2,690), despite homes valued slightly higher than the national median.
County Taxes Vary Dramatically Across the State
Delaware's three counties show striking variation: Sussex County's effective rate of 0.331% is less than half New Castle County's 0.741%, creating a median tax spread of $1,273 between lowest and highest. This county-level inequality means where you buy in Delaware matters significantly for your tax bill.
A Typical Delaware Home, A Modest Tax Bill
The median Delaware home is worth $324,567 and carries an annual property tax of $1,649—roughly $137 per month. This combination of reasonable home values and low tax rates keeps housing costs among the nation's most competitive.
New Castle Bears the Highest Tax Burden
New Castle County, home to Wilmington and the state's urban core, carries a 0.741% effective rate and $2,444 median tax bill—substantially higher than rural Sussex County's 0.331% rate and $1,171 bill. Kent County, the middle ground, taxes residents at 0.458% with a $1,331 median bill, reflecting its balanced mix of suburban and rural character.
Delaware: The Low-Tax Haven for Homeowners
Delaware is definitively a low-tax state, ranking among the nation's cheapest for property taxation—a major draw for cost-conscious homeowners. If affordability is your priority, Sussex County offers exceptional savings; those willing to pay more for urban amenities can find them in New Castle County's Wilmington area at rates still well below the national average.
